ORE-BELT EDGER.

To all whom, it may concern Be it known that ll, ALBERT W. HARP, a

. citizen of the United'States, residing at Angels Camp, in the county of Calaveras and State of California, have invented new and useful Improvements in Ore-Belt Edgers, of which the following is a specification.

This invention relates to vulcanizers and especially to vulcanizers for repairing and splicing the body or edges of conveyer belts.

Conveyer belts, particularly those used for carrying ore, frequently become worn or cut on their carrying surface and become damaged at their edges, causing the ore to' necessitating the removal of the belt from I its ordinary position.

The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a plan view showing the device appliedto a conveyer belt, whose edge is to be repaired. Fig. 2 is a cross-section on line XX, Fig. 1. Fig. 3 is an end elevation of the apparatus in position for use as an edger, as in Figs. 1 and 2; the lower heating un'it being broken away to show a h'eating coil. Fig. 4 is an elevation similar to Fig. 1, showing the belt in cross-section and theinvention used to splice or repair the body of the belt. Fig. 5 is a perspective of a combination edger. Fig. 6 is 'a plan in par- -tial section of the underneath heating element. I

The ore or other conveyer belt which is to be repaired is shown at A and has the edges 2. Belts of this character have the edges 2 of different configuration, there being a number of ore conveyer belts of different forms on the market at the present time. The presentinvention is adapted for Specification of Letters Patent.

use on any conveyer belt regardless of the configuration of the edges.

' In repairing a conveyer belt with my invention, rubber cement, together with the same kind of material of which the conveyer beltis constructed, is used, as some conveyer belts are made of rubber and fabric, while others are made of canvas only.

The rollers which support the conveyer belt are shown at 3, and are carried by the wooden sills l of the machine frame. Adapted to engage with the underside of the sills, 4 are adjustable, angular arms 5, with'pivoted latches 6 adapted to hook over the top of the sills; and these arms connect with crossbars formed of two parts 7-S which are adjustably connected by bolts and nuts 9, so that the arms 5 which engage the sills may be moved toward and away from each other according to the distance the stringersare apart, thereby adapting the device to any width of conveyer belt. These crossbars are braced by side bars 10 which have clamps 11 at their ends that embrace the arms 5 and are vertically adjustable thereon, and are secured thereto by screws 12.

The bars 10 carry screws 13 which act, when the device is used to splice or repair the edges of the-belt, to bear againstand adjustably hold in position the combina tion adjustable outside edger 14:, which is shown in detail in Fig. 5. This edger has faces 1516-17 of different configuration covering a wide range of contours existing on the outer edges of conveyer belts now on the market, so that the invention is adapted for use 'in connection with any commercial belt. The screws 13 hold the edger 14c snugly against the outer face of the belt edge, as shown in Fig. 2.

Extending under, and braced against, the crossbars 78 is a bar 19 which has screws 20 adapted to bear upon the combination, reversible, inner edger and splicer 22. The splicer has a hole into which fits a standard electric heating coil 24 having terminals 25 for connection to any electric circuit whose voltage is sufficient to effect the proper temperature suitable for splicing.

The splicer 22 constitutes, as shown in Fig. 2, an inner edger which has opposite faces 28- 29 of different configuration, so

' that-it is adapted to fit the edge of any of the ordinary conveyer belts. This inner edge is pivotally connected with rods 31 carried on clamps 33 which are adjustable moved crosswise of the belt, so that it will fit snugly against the edge of the conveyer belt, no matter what the width of the latter may be. The inner edger 22 has flanges 35 which are adapted to overlap the outside edger 14 and thus rigidly clamp the edge 2.

The purpose of the screws 20 is to evenly transmit pressure to the edge of the belt through the splicer 22 and edgers. The adjustable clamps 33 and the screws 13 enable the respective edgers to be shifted to any desired position so that they will always properly contact with the edge of the belt.

The outside edger let has a longitudinal pocket or hole toreceive a heating coil 36. similar to the coil 24 of the inner edger 22. Operating in conjunction with'the combined edgers and heating units 22-24 is an underneath heating unit 38 which is preferably made in two parts, suitably held together,

as by the bolts 39, passing through lugs 40 on the sides of the section. This heating unit has apertures .41, Fig. 6, adapted to contain heating units l2; and the apertures are interconnected, as shown at 4-3, Fig. 6, so that if a gasolene torch or steam coil is desired to be substituted for the electrical. heating coils 42, the heat may readily pass from one chamber to another, and thus heat the entire splicer uniformly.

lln practice, when the belt needs repairing, either at the edge or on its body, the machine is stopped, the belt lifted and a plank, represented at 44, is shoved under the belt and allowed to rest on the sills 4; the purpose of the plank being to support the heater 38. The hanger represented by the arms 5 and crossbars 7-8 is suitably adjusted to the frame in accordance with the width of the belt. llf an edge of the belt is to be repaired, then the parts are adjusted as shown in Fig. 2; the outside I edger 14: being supported against the out side edge of the belt and on the edge of the underneath heater 38 which projects beyond the belt and suitably held in place by the bar 10 and adjusting screws 13. Next,

the inside edger 22 is shoved up against the inside edge of the belt and held snug against the belt edge by means of the rods 31 and clamps 33. the belt having been previously prepared for the vulcanizing operation; the several heating units 2214l--38 are heatedto the proper temperature and for a sufficient length of time to conclude the job.

If the body of the belt is to be prepared,

or vulcanized, the parts are arranged, as shown in Fig: 4, in which only the two heaters 22 and 38 are used; the heater. 22 being reversed so as to bring its broad, flat side with the flanges 35 down on the belt.

4, bymeans of clamp screws 20.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A vulcanizing outfit for conveyer belts, comprising a frame extending crosswise over the belt and having means to grip the frame on which said belt travels, at the two sides of the belt, .a vulcanizing element with heating means supported from beneath the belt and on which the belt rests, and a vulcanizing element with heating means on top the belt and helddown thereon in opposition to the underneath vulcanizing element by means carried by said frame.

4. In a belt conveyer edger and splicer, the combination with means for supporting the belt conveyer, of a frame, an outside edger adjustably attached to said frame, and an inside heater adapted. to coiiperate with the edge of the belt conveyer, said heater being adjustable in relation to the means forsupporting the belt conveyer.

5. lln a belt edger and splicer, the combination with means for supporting the belt, of a separate vulcanizing attachment having independent outside and inside adjustable edgers, and heating means carried by said edgers.
